Castaldo gold label shrinkage factor

Does anyone know the percent shrinkage for Castaldo Gold Label?
Every google search returns the “No Shrink Pink”.

I am making a 3D model I plan to make a mold of. I have a ton of
Gold Label, so I thought I would just scale the model by x% and then
make the mold. I need it kind of close (I have a parcel of 8x6mm
stones and will bezel set one in each).

Our experience is that the Castaldo Gold shrinks about 3%. Not so
much for stones your size. Just don’t make the model too thin so that
you can clean out the inside of the bezel if needed.

Have fun and make lots of jewelry.
